The man who has God for his treasure has all things in One. Many ordinary treasures may be denied him, or if he is allowed to have them, the enjoyment of them will be so tempered that they will never be necessary to his happiness. Or if he must see them go, one after one, he will scarcely feel a sense of loss, for having the Source of all things he has in One all satisfaction, all pleasure, all delight. Whatever he may lose he has actually lost nothing, for he now has it all in One, and he has it purely, legitimately, and forever (A.W. Tozer, The Pursuit of God, 16).
This nothing more than a wonderful way to restate the sentiment of Psalm 73:25-26. It is an antidote for materialism and a keen reminder of the very thing for which we were created, to love God and to enjoy Him forever.
